I well remember this guy on BBC Home Service Saturday night Music Hall &c:-

"G. H. Elliott (November 1882–19 November 1962) was a British music hall singer and dancer. He was born George Henry Elliott in Rochdale, Lancashire in 1882. Known as the "Chocolate Coloured Coon..." - Wikipedia

who went on with the same nickname, which iirc nobody thought in any way odd, till the 1950s.
